WIRE-WEAVING 100M Application filed June 11.. 1928, Serial No. 28 1, 599, and in :Germany February 4, 1925. I

In the process of weaving wire fabric with wefts too thick to be dealt with by means of shuttles it has heretofore been usual to crimp and cut the weft wires in a separate machine, and then to insert them by hand. According to my invention the loom itself is provided with a crimper arranged at one side of the shed and operating so that the push given to the wire by the crimping insert it into the shed. There is, consequently, no work to be done between the crimping and insertion of the weft wires, and a single man can attend to the loom.

A loom according to the invention is shown in the annexed drawings, in which Fig. 1 is a front elevation, Fig. 2 a side elevation, and Fig. 3 a plan view. Figs. 4 to 8 show details.

In the drawings 1 represents the lay, and 2 the fabric. At one side of the fabric there is a wire crimper 3 which is on the lay and has two ribbed wheels 4, 5 (Fig. 6) mounted on spindles 6 and 7 respectively, the spindles being carried by levers 8 and 9 fixed to 4 shafts 10 and 11, which are connected by gears 12 and 13. The gear wheel 12 meshes with a gear wheel 17 on the spindle 6, and the gear wheel 13 meshes with a gear wheel on the spindle 7 not shown in the drawings. On the shaft 11 there is a gear wheel 14 meshing with a gear wheel 16 on a shaft 15. The shaft is driven by means of a belt and a pulley 19 connected by a clutch 26 with a shaft 21 mounted in the frame 20, the belt 25 passing over a pulley 23 coaxial with the lay shaft 22, and over a tensioning roller 24 and a pulley 18 on the shaft 15.

The wire crimper 3 comes into operation when the lay 1 is at rest in its rearward position, the clutch 26 being then thrown into engagement. The weft wire coming from a reel passes through a guide or straightening device 27 to the ribbed crimping wheels 4 and 5. By the stress due to the bending it is pushed into the shed.

When the wire has passed through the shed it strikes an electric contact 28 (Fig. 5) and closes the circuit of an electromagnet 29, whose armature 31 is fixed to the lever of the clutch 26, disengages the clutch,

controllinga clutch 34 in 'theloom actuating mechanism, so that when the clutch 26(is disengaged the clutch 34is engaged, andthe laybeats up the weft. Theinovement of thelayactuates a cutter 35 (Fig. 4) having a fixed shearing plate 36, with a hole 37 therein for the-weftwire, and a. moving blade 38 having a slot 39, wh0se loweredge:

.is a cuttingedge. The blade is actuatedby means. of a'bell crank lever 40 and a cord 41 pulled by the, forward movement of the lay.

When the lay returns an abutment 42- thereon (Fig. 6) actuates a bell crank lever i drive the wire'crimper,

Instead of keeping the at rest during the crimping the arrangement may be such that during thecrimping it moves sufficiently slowly to avoidinterference with the crimping. The construction is in that case more simple, as there is no mechanism connecting" the crimper clutch to the main clutch.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A wire fabric loom having incorporated therewith, a lay, a crimper on the lay for the weft wires, arranged at one side of the shed, operating so that the movement imparted to the wires by the crimping thereof introduces them into the shed.

. 2. A loom as claimed in claim 1, wherein the crimper is put into operation while the lay is at rest in its rearward position, is moving with retardation. i

3. A loom as claimed in claim 1, wherein the crimper is driven by belt and pulley gear so that the bender is stopped: ,The lever .30 is, connected by links 32 to a lever 33 including a pulley having its axis in line Weft Wires to close the circuit of an electromagnet controlling a clutch for driving the Wire bender.

6. A wire fabric loom having incorporated therewith a lay, a crimper on the lay for the Weft Wires, arranged at one side of the shed, operating so that the movement: imparted to the wireeby' the crimping thereof introduces them into the shed and also having a Wire cutter actuated by the beating. up motion of the lay, for cutting the Weft Wire and a cord to actuate said cutter, said cordbeing attached to the frame of the loom and tensioned by the beating tip motion of the lay.

7. A loom as claimed in claim 1, having an electric contact actuatable by insertion of theweft wires to clese theieireaifi of an elec-- t romagnet controllin clutch for drivin the wire crinrper, and a c'l'ittch ontrolhng the loom actuating mechanism and to which the first named clutch is conneeted se that engag'etne'n't of either clutch causes; the other to disengaged. I

S. A 100m as claimed claim 1*,- having an ele trie' contact actuatable by insertion of the weft wires" to close the circuit of elecromagnet controlling a, clutch for drivin the wire crimper, and clutch controllin the loom actuating mechanism and to which the first named clutchis connected so that engagement of either cl'u'tch causesthe other to be disengaged, said clutch the drivin mechanism of the 10cm being dis'engageahle by meehahiemace-rated by the lay' on the completion of its retuT'nstroke after beating up the weft. I

In testimony whereof I my signature.
